ROBERT EUGENE runNER, on. NORFOLK, VIRGINIA.

1'0 ctZZ whom it may concern;

Be it known that I, RoBERi' E'UGENEYTURJ NER, a citizen of the United States, residing at,Nprfolk, in the county of Norfolkand State of Virginia, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

' Fig. 6 is a plan of the same.

My invention relates to type-writing machines and paper-carriages therefor, and one of the primary objects is to increase the mechanical control of the pa er-carriage with a resultant increase in'spee Another object of my invention is to provide certain peculiar construction of carri ages which will enable it to return automatically when the end of the Writing-line is reached, also to return same by pressing a key-lever on the keyboard to returnthe car riage at any oint of its stroke and to cushion the impact t ereof occasioned by the abrupt stgppage of the carriage.

further object of my invention is to rovide certain tracks or runways for the ictionless operation of the carriage.

A further object of the invention is to effect the line-spacing by manual and automatic means.

With the above and other objects in view my invention'consists of certain novel improvements shown in simple embodiments in the accompanying drawings, forming a part of this specification, in which- Figure l is a s ctional elevation of the t *pe writing machine and showsthe genera arrangement of the mechanism. ig. 2 is an enlarged end elevation of the carriage and its operating mechanism.

The other ends of the belts or tapes are circumferentially secured to the drum 35, which is actuated through its shaft 35". In this manner motion is imparted to the carriage by means of suitable motors and gearing, as will be hereinafter described.

In place of the belts or bands 33 and 34 I may employ the'rack 36, Figs. 2 and 39, fastened to some suitable point beneath the carriage 14 and driven by a toothed annulus or gear-wheel attached to the belt or tape drum 35.

Referring to Fig. 4, which being a plan more clearly shows the automatic carriagereturn'mechanism indicated in Figs. 1, 2, and 3.) i

38 is a maximum-powered spring or other motor having a gear-wheel 38 and holdingratchet 38. The wheel 38* meshes with a pinion 39'on the shaft or belt-drum axle 35, which also carries the large center wheel 40. The gear-wheel 40 alternately meshes with the clutch-wheel 41, which is adapted to engage and disengage the wheel 40 at certain intervals. during the lateral movement of the The wheel 41 has a gear 42, forming a part of and concentric with it,'but usually of a smaller diameter. The two wheels 41 and 42 are rockably supported upon the rocker-arm 43 and rotatorily pivoted thereto by the pin 44, the arm 43 being pivoted at 45, Fi 2.

46 i: a minimum-powered spring provided with a holding ratchet wheel 47 and rotating the si. .ft 48, upon which are fixed two pinions 49 and 49. The springs 38 and 46 are wound by pawls acting on ratchet-wheels in the usual manner but I do notshow such.

in Fig. 2 the spring 47 is shown at the The dotted lines 47 show a better position,: which corresponds approximately to the position shown in Fig. 4. The pinion 49 is adapted to engage the wheel 42 simultaneously with the contact of the wheels 40 and 41. i

50 is awheelsimilar to that at 41'and having a concentric gear-wheel 5]. of a smaller diameter forining apart thereof.

The'wheels 50 and 51 are supported upon the rocker-ar1n 52 and rotating around the axle or pin 53.'

The rocker-arm 53, with its gear-wheels, is

held in proper contact with its communicatiiig trainof gears by the spring 53,- located a short distance about the rocker-arm pivotblock connection 53 Fig. 3.

54 is a shaft supporting the intermediateor idle wheel 55, which alternately meshes with the wheel 50 andoccurs simultaneously with the lenga ementof the wheel 51 and pinion 49". e axle or'shaft 54 is fixed to outnal-platFi-S, which also supports the shafts 35 and48 forlrotatinn. The idle wheel 55 is in mesh with the wheel 57, located arms 59and 62 forming a bell-crank by which the clutch-gearing is thrown in and out of engagement with the described train of gears. 11 ike manner the rear rocker-arm 52 is con: nected to a link 59, theother end thereof being connected, as at 59, to a similar arm of the bell-crank, as will be described hereinafter. The link, Fi 4, transmits motion to the rocker-arm by t e bell-crank 61 and 62, pivoted to the controlling or shifting bar 64. 65 is one arm of the rear bell-crank; which is provided with a hub or boss portion 66, secured to the rear shifting-rod 67, rotatorily supported in the step-bearing 67, 68 bein the other armof the bell-crank and is pivoted to the shifting bar 64 at 69-. The bellcranks, Fig. 4, are oppositely disposed, so that the clutch-wheels 41, 42, 50, and 51 are alternately thrownin and out of gear with the wheels 40 and 55 and the pinions 49 and 49".

70, Fig. 2, represents standards for 'slidably supporting the bar 64 which is provided with a toothed or rack end 71, having a transverse roller 72, which assumes the position shown at 72, Fig. 11, by dotted lineswhen on the opposite sideof the traverse-bar 7'5.

Referring to Figs. 2 and 11, the carriage 14 is provided with lateral projection or bar-'7 3, either apart of or aflixed to the bottom of the carriage and traveling therewith and is therefore in a depending position and of a length to correspond to the length of the writing line. The traverse-bar 73 is rovided with rounded or pointed ends 73", ig.

11, to permit the roller 72 on the rack 71 to pass around the ends of the bar 73 and traverse first one side and then the other. The rack 71 meshes-with the segmental gear 7 4, pivoted at 75 on the frame 1, Fig. 2, and is provided with an arm 7 6, to which is fastened the operating-rod 77 the lower end of the rod 77 being connected by resilient means to a special key-lever 79.

In Figs. 21 and 22 I show a preferable arrangement for the resilient connection of the rod 77 to the key-lever 79 instead of the arrangement shown in Fig. 1. The rod 77 is divided, and'at the point of division there are fixed two plates 77 and 77", Fig. 21, the

ends of the rods passing. through the lates,

forming a rectangular cage for the sprln'g 78, as shown. The plate 7 7*, when operated by the middle spacelever 79, which is arched, so

as to bridge the universal bar 9, to prevent.

t e spring 78 takes up-the downward motion of'the lever 79wh'en thesegmental gear 74 is 42,51, and 52 without-disturbing the posi end or limit of its stroke.

prevented from performing its function the traverse bar 73. Therefore a pull upon the rod 77 causes the parts 77 and 77 to approach each other and compress the spring 78.

The above-described operation takes place automatically when the carriage reaches the It is obvious that in writing short lines or one or more words it is necessary to return the carriage to its initial position before the end of the stroke;

This operation I accomplish by means of the limit-release key-lever'82, Figs. 14 and 15, having an arched portion 82 for bridging the universal bar 9, operated by the levers 82.

In order to shift the clutch gear-wheels 41,

, 87 is a spring encircling the rod 84 and between the lugs 85 and 86.

When the device is operated by hand, the

. g' 85 changes to the position shown by the dotted lines 87 which returns the carriage, the rack 71 having a direction of movement when automatically operated as shown by the arrow. The rack 71 is notactuated when the changin is done by hand.

When the keyever 82* is released to the position shown by the full lines, the segmental gear is in operative position for effecting the change when the roller 72 runs upon the front side of the traverse-bar 7 3. The bar 64 is connected to one arm '88 of the bell-crank and pivoted at 89, the other arm of which is ivotally connected to a' link or rod- 90, attached to the key-lever 812 at 91.

Referring 'to Fig. 4, which is the position assumed by the mechanism for ordinary step-by-step spacing movement produced by the escapement mechanism in writing, the step-by-step motion is produced by the motor-spring 46, and its movement is therefore slow, except when tabulating during the action of the spring 46 the spring 48 is being put into tension in order to store up energy for the return stroke of the carriage, which the spring 46 is enabled to do, although the weaker spring on account of its power being augmented by gearing, the wheels 41 and 4:? being engaged with the wheel and the pmion- 49, while those at and 51 are disen- ..gaged from the wheel and the pinion 49-. -When,-tlie carriage reaches a certain point,

the automatic shifting of the gear-wheels on the rocker-arms 43 and 52 connect the train of gears, so as to change the relative strength of the springs, thus making the spring 38 exert the greater force for the carriage return, yet capable of being rewound by the periodic movement of the spring 46 when connected to the power-multiplying gear-wheel train.

' In Fig. 4 the sprmg 46"is in operation driving the carriage to the left, as usual, the pinion 49 transmitting the motion through the wheels 41 and 42 to the large wheel 40, which is approximately three times the diameter of the wheel 41 and is therefore in gear for power.

The spring 38 is provided with the'wheel 38 and 1s ap roximately twice the diameter of the whee 39 which drives it, and thus winds the spring. I

When the wheels 41 and 4' are out and the \1\"heels"50'anil 51 are rag-sag: he spring 38 exerts power to drive .the wheel 38", the smaller wheel 39, and the larger wheel 40, thou h it is not in meshing contact with the wheel 41. It transmits no motion to the other wheels and is consequently idle during the return of the carriage. The spring 38 through the shaft or axle 35, rotates the wheels 55 and 57 and through the wheels 50 and 51 to the pinion 49 on the shaft 48 and winds the spring 46. The s rin stronger than that at 46. T ere ore the momentum of the carriage during its quick return, together with the gear-wheels 51 55 57 and the'pinion 49- is suflicient to wind it.

v The carriage being provided with balhbearing knife-edge rollers and wheels running on a glass track, the resistance of the carriage a moving force is extremely slight. The wheels 41 and 42 are simultaneously disengaged. Therefore holding-ratchets are not used, except when necessary to wind the springs by hand. When it isrequired to return the carriage by hand, as is the case with rdinary mach nes, the wheels 41, 42, 50, and 51 are held permanently out of gear by suitable means.

As already described, the automatic return of the carriage is effected by the segmental ear 74, which causes the rack 71 to be pulled orward or-backward when the roller 72 traverses the back and front sides of the bar 73,

thus operating the bar '64, which'throws the proper earing into position. The rod 77- operates t 1e segmental gear 74 by means' of the bar 79, attached to and operated by the too space-bar 81, the spring 78 permitting a downward pull of the space-bar when spacing during the printing operation without operating the segmental gear until the-carriage.

has reached acertain point. When the segmental gear 74 is released, the sprlng 78 1s suiiiciently strong to give the same effect as if the bar 77 was ri idly connected. to the bar 79. The traversear 73 is 0 such a length as to correspond to the length of thewritmg- I line, the roller 72 being normally in the rear stroke.

gThe shaft 94 is ratchet-wheel 95, concentric with and below of the bar 73 when writing in'the ordinary manner.

It willbe thus seen that the bar 73 acts as a check or look against the forward motion of the rack 71, holding the proper gearing in position until such times as it is necessary to change them to return the carriage either automatically at the end of the writing-line or by hand at any point of the carriage transverse \Vhen the carriage is returned to the initial point or commencement of the writingline, there is considerable impact or jar imparted thereto due to the sudden stoppage.

In order to arrest the carriage quietly,I provide varotary cushion consisting of a cylindrical boX or case 92, Fig. 24, having a fill-. ing-plug 92 for the fluid, which consists of oil, glycerin, or other liquid with which the ox or case is filled to a more or less depth, according to circumstances. i

93 is a bearing-sleeve on the cushion cylinder or box 92.

94 is the buffer or paddle-shaft, having a gearwhe'el 95 on its upper end which meshes with the rack 95, placed upon a suitable point on the carriage 14 and in mesh with the wheel 95 at a point near the limit of the stroke of the carriage, and therefore in striking alinement when out of ria'ge is at the beginning .ofthe writing-line. The rack 95" is mounted upon the bar 95*, 41, which contains a horizontal slot 95 for adjustment of the rack by the screw 95 to enable the cushioning effect to take effect earlier or later in the stroke of the carriage. provided with 'a backing the gear-wheel 95, but rotating with it.

. 97 'is a pawl-case fastened to the shaft 94, in which is placed oppositely-disposed pawls 98, held upon the teeth of the ratchet-wheel 96 by the springs 98. The object of the ratchet and pawls is to allow the rotation of rotation of the paddles offers little retarding 'erin, or other fluid container the shaft only whenthe carriage is nearly at the end of the writin -linegbut during the opposite movement t ereof the pawls pass over the teeth of the ratchet-wheel without impart-ing motion to or offering any resistance. to the escapeinent mechanism. 99 is a coneshaped pivot end on the lower art of the shaft 94 andfits with a correspont ing-shaped step-bearing 100, "located within and upon the bottom of the case or base 92.

In order that the desired line-stpacing may be accomplished automatically a I employ the mechanism shown in ig. 29.

The platen 2 is provided with two gearwheels 104 and 105 u on the ends thereof, which mesh with the w eels 106 and 106 on the square or polygonal shaft 107. A

The gears 106 and 106 are driven by the gear-wheel 108, slidably mounted uponthe shaft 107, which is also rotated by theshrouded wheel 109, slidably located on the driving-shaft 110, having a round portion 1 Fig. 29, supported in the standard 1 10*, Fig. 39, as will be more fully explained hereinafter. The purpose of having the wheels 108 and 109, Fig. 29, slidable is to enable them to remain in mesh though the carriage be moved beyond the'm ain frame'of the machine as the end of the carriage passes beyond the center of the frame in its transverse movement. Therefore both gears will slide to keep together; The flanges on the wheel 109 carry its mating wheel with it.

VVhenthe platen is elevated for printing u per-case characters, it is evident 'that'the w eels'lOS and 109 will be separated, and to overcome this I provide a bevel or .miter Wheel 111, having a spring 112, which allows it to keep in mesh with the bevel-wheel 113 and slide upon each other when the platen is elevated and to return to their normal positions, as shown by the full lines on F i 29 and by the dotted lines at the left 0 the bevel-wheel 111. The wheels 111 and 113 are connected to the wheels 108 and 109 by a ring 112 acting to cause the wheel 111 to side upon 113 when the platen is lifted, yet kept in mesh by the wheels sliding axially upon the toothed portions.

In this my present invention I have assumed that the platen is vertically lifted for case changes,-but I am not confined to such, asI may adopt my invention readily to eflfipt the case changes by a horizontal or back-a-iitl; forth movement of the platen. The shifting of the platen for case changes is lifting toe or cam 114, Figs. 29, 34, and 35, which is made in two separable halves, as shown at 114 and 114", Fig. 35, inclosing the balls 115. The cam or toe is pivoted at 116 and provided with an arm 117, to which the rod 118 is attached, so as to enable the cam to be operated from the keyboard inthe -or-- dinary manner.

The balls are disposed on the edge of the cam, as indicated in Fig. 34.

In order to guide the carriage 1 1 in ver- 29, 36, and'37, having e proje'ction123, tie guide-pins 124, which are usually of a square or rectangular cross-section, passing through a correspondingaperture in the carriage base or bottomiplete and are for guiding t 1e cer-v ria e for a vertical nieveinent.
